API function

## NAME

gnutls\_x509\_aia\_get - API function

## SYNOPSIS

**#include \<gnutls/x509-ext.h\>**

**int gnutls\_x509\_aia\_get(gnutls\_x509\_aia\_t** *aia***, unsigned int** *seq***, gnutls\_datum\_t \*** *oid***, unsigned \*** *san\_type***, gnutls\_datum\_t \*** *san***);**

## ARGUMENTS

- gnutls\_x509\_aia\_t aia

  The authority info access

- unsigned int seq

  specifies the sequence number of the access descriptor (0 for the first one, 1 for the second etc.)

- gnutls\_datum\_t \* oid

  the type of available data; to be treated as constant.

- unsigned \* san\_type

  Will hold the type of the name of **gnutls\_subject\_alt\_names\_t** (may be null).

- gnutls\_datum\_t \* san

  the access location name; to be treated as constant (may be null).

## DESCRIPTION

This function reads from the Authority Information Access type.

The  *seq* input parameter is used to indicate which member of the sequence the caller is interested in.  The first member is 0, the second member 1 and so on.  When the  *seq* value is out of bounds, **GNUTLS\_E\_REQUESTED\_DATA\_NOT\_AVAILABLE** is returned.

Typically  *oid* is **GNUTLS\_OID\_AD\_CAISSUERS** or **GNUTLS\_OID\_AD\_OCSP**.

## RETURNS

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error value.

## SINCE

3\.3.0
